Halogen to Bi-Xenon - Kufatec Interface

[fly300kts]

I did an upgrade today to I finally took the time to take some pictures. I know that another DIY does exist on another site but I think this one is more detailed

On Driver & Passenger side, plug the harness
Left Side



Right Side



Passenger Side:
Secure the wire to the existing harness



Remove the seal from the front frame



Insert the wire inside the seal grove and reinstall the seal in place





Install and secure both headlights. Connect the new Harness to the headlight.
Using zip ties, run both wired along the brake line. Both wires will exit the wheel well through the same hole than the rigid brake like.



Start the car and turn the wheel completely to the right. Turn off the car. Without removing any component, like the wheel for example, you will see this large grommet.



Pull on the grommet



Now, inside the car, remove the lower panel



Locate this connector by the relays
Using a small screwdriver, pull down the orange locking tab (already unlocked on the picture) and the connector will slide out his slot



Connector close up



Cut the small zip tie and slide out the pink tab



Now the grey cover will slide out the connector assembly



Let’s go back to the grommet in the wheel well. Using a razor blade or other, cut a small part of one of the sticking tube. The target is to obtain a hole as small as possible, just to be able to run the 2 wires. In case you cut too far, no worries, you can always, once the grommet will be back in place, apply some silicone from the inside of the car. Run the wire inside the orifice you just made.



Reinstall the grommet in place. Make sure that the 2 wires are secured inside the wheel well. I was not able to take a picture due to the lack of room but I added a zip tie, securing the 2 wires and the brake line.
Make sure the grommet is correctly secured inside the grove. If you cut a hole too big, you can add the silicone from here



Now you are going to connect the wires. These wires are the Hi-Beam command so it does not really matter as far as Left or Right Headlight but the position on the connector is critical. They have to be on slot 21 & 22. On this close up, to make sure that you are correctly oriented, the # 17 (red circle) on the connected should be on the left. The 2 blue arrows show the wires location, slot 21 & 22.



Make sure that the connector is correctly oriented. Just push on the wire and it will click and lock itself in place



The result should look like this



Put the connector back together and install a new zip tie



Secure the excess length of wires and you are done !!



Let me know if any question

all i can say, is from what i can see...that is one sexy ibis white a4

That's one beat down thumb you got Phil.

Printing this for my install. Thanks!

[Coderedpl]

That is one way of doing it. Another is going around the area of the ECU. There is a little rubber grommet there too, many times it's used to route the tubing from the boost gauge. That's the way I routed mine. For the passenger side i went around the passenger side seal next to the intake.

[Doctor]

Well done for helping the community as always Phil.

[FASTONE]

Phil,
This is what I am talking about, very sharp!!! I still have not installed the v4's yet but will do sometime next month!!! Thanks!

[felondnb]

I routed the extra wire through the ECU too, but to get the cover off, you need to remove the wiper & a flexible socket set helps.

I was also running a 4 AWG power cable so I did both through the ECU into the driver's footwell, then ran the power to the back under the door shut/sill trims.

[GA42.0T]

Great DIY Phil, as always. Used it last weekend for my install. If I may be so bold as to suggest one small edit for the truly novice DIY'er:

Using zip ties, run both wired along the brake line. Both wires will exit the engine compartment and enter the wheel well through the same hole as the rigid brake like. See yellow arrow below.





Start the car and turn the wheel completely to the right. Turn off the car. Without removing any component, like the wheel for example, you will see this large grommet.

Also, I had to take my wheel off cause I couldn't see shirt in there - and I'm only lowered on Eibach springs.

Thanks again.

I want xenons.... but am to afraid to mess with anything electrical on my car.... I will install suspension, exhaust ect... but hate deing with electrical work.

[GA42.0T]

This was really easy. Barely even qualifies as "electrical work." Just run those two wires and plug them where Phil indicated. That and plug the light into the harness. Easy peasy.

I was nervous too, but and so glad I did it. The night visibality is so much better. Add how cool they look and it's totally worth it.

[Weem]

im going to be doing this upgrade next week but im confused on one thing....a separate harness is needed for each side? i was under the impression only 1 total was needed


thanks

[GA42.0T]

One kufatec harness has two connecters for, duh, two headlights. Basically the connecters for halogen lights don't fit the connectors for xenon. Xenon has one or two more prongs in the connectors, so you physically cannot connect xenon connectors into halogen harness. Won't click in there.

So kufatec harness is an adaptor between your stock halogen harness and you new xenon connector. And the extra wire in the kufatec harness corresponds to the extra prong in the xenon connector. This is the wire which Phil demonstrates in this DIY how to run and connect to CPU.

I can't find the harness on kufatec's website for some odd reason.... but the picture in the "kit" shows the harness

http://kufatec.com/index.php?main_pa...roducts_id=162


you can see that it's actually 2 separate one, one for each side, but they wrap the high beam wires together, so that process "ties" the 2 pieces into 1.
Perhaps they have updated the design since then and no longer wraps them together, but either way, it's the same idea: one adapter on each side, plus the really long high beam wires.

yeah i just relooked at the harness and it was just all coiled up...sorry for the mix up!!

[brucebanner]

im hoping to get my bixenons soon, but i gotta say that im not looking forward to running the wires and install. im terrible with running wires and fitting in small places. when you guys talk about running it through ECU, where exactly is that? any pics. I just want the easiest way possible

[fly300kts]

just follow my DIY

yea thats what I plan to do, the only part that confuses me is because i dont know where the break lines or anything is. but i also have never looked under my hood for stuff like that. im just kinda worried about the part of getting the wires to the grommet in the wheel well, cutting the little hole, and getting the wires into the car.

but ill just have to wait til i get everything and go to install before i start worrying about this stuff right now i guess.

and im probably 2-3 weeks out maybe even a month from getting everything im assuming anyways

Relax, once you will have everything in front of you, you will be fine
If still, you can figure it out, well, find a buddy who does of pay a Mechanic. This is really basic stuff !!

ok

[Audi Skate Snow]

great write up. props for sure!

[72mako]

Great write up Phil, as always. Thank you for making the point about the right and left high beam wires, when I did mine I couldn't figure out whether the slots were assigned to a right and left headlight or not. I'm pretty sure I followed the break line into the wheel well but it's been almost a year since I did my install.

Would these just be plug and play? Or would I have to use vagcom to tell the car I have the xenons?

You will need to WAGcom the car to enable the High Beam function

phil

[event]

I tucked mine the same way, have had Xenons wired up for like 2 months now and still haven't VAG'd them, haha... Nice write up, I had to fumble around when I did it.

[rvca3112]

Wagcom? I thought it was vagcom. Am I wrong?

[rvca3112]

What vagcom settings do I have to go into to tell the car it has xenons as opposed to halogens?

[kurupt_hawaiian]

Just upgraded my halogens to Bi-xenons today following this walkthrough. Thanks!

Hi Phil! First of all very nice and detailed post. I have a lot of your threads bookmarked for future DIY i'm planning to do..
Anyway.. have you considered buying 14 pin adapter and reconnecting all wires into it and running 2 additional wires back to 32 pin harness?
1J0973737 ($6 part from VW dealer $7.71 from Audi) is the part that is that 14 pin connector, so supposedly one can take out all the wires from halogen plug plug them into it? and then run 2 more wires ? is that true?

[fly300kts]

Can't answer, I do not mess with harnesses unless obsolete
I just buy my Kufatec interfaces

i tried connecting the headlight through the kufatec harness - and lights do turn on just not the xenon bulb. have new bulbs in there. what could it be? i just disconnected one connector from the halogen, plugged in the harness into it and into the headlight..xenon bulb doesn't ignite when i turn lights on but other bulbs light up ok.. i didn't vagcom code it.. what could be the issue?

[kurupt_hawaiian]

You need to vag it!

[kurupt_hawaiian]

I converted my halogens to bi-xenons about 2 months ago. Before I did the vag-com it would flicker which is bad for the xenons. Vag it and it will work fine.

[null]

ok i just spent an hour with vagcom trying all possible things i can think of with these lights. i have adaptive with AFS headlights with new d1s bulbs and ballasts. I plugged in the harness I bought from Jens and I vagcommed 09 controller to 00033 which bi-xenon no drl / usa. same thing - my xenon lights do not turn on. i dont understand where do i go to code so they are not AFS but regular xenons? where in vagcom is it? when i go to 029 left light controller module - it doesnt connect.
I read codes and vagcom in 09 controller module is telling code 000978 left light short, 000979 right light short.. what to do ? i tried swapping ballasts, i tried swapping headlamps from left to right..the d1s bulbs are brand new generic philips bulbs - they don't have to be audi or anything right? ?
anybody please hlp.. i swear i hear motors or something clicking when i turn of the light/ remove key from ignition - but no xenon light

[lenti]

i hope i dont have any problems with mine l8ter...
wich code to i need to change from Halogen to Xenon on a EU car?
i have vag-com cable

[Firefox250]

I have the same question

[lenti]

well right know you should have 01012 change it to 01021 then ure done :D

[Firefox250]

well right know you should have 01012 change it to 01021 then ure done :D

Thank you lenti, is that code for non adaptive Bi-xenons? Whats the code for e-codes?

[lenti]

Thank you lenti, is that code for non adaptive Bi-xenons? Whats the code for e-codes?

The first code 01012 was for the Halogens, thats what i had on mine (Sweden)
for the Xenons with DRL you need to change 12 to 21 instead.

[Firefox250]

After installing these Bi-xenons do you have adjust the beam height? If so where? I looked in the Bently manual and did not see anything.

[kurupt_hawaiian]

There are two white screws on each headlight. One to go left and right, the other to go up and down.
